AUGUST ROSENTHAL, OF WEST ALLIS, WISCONSIN, ASSIGNO'R TO ROSENTHAL MANUFACTURING ('10-, OF WEST ALLIS, VIISCONSIIN.

CORN I-IUSKER.

Application filed March 10,

To all whom it may concern:

Be it known that I, AUGUST RosnN'rHAL, a citizen of the United States,and resident of West Allis, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in CornHuskers; and I do hereby declare that the following is a full, clear,and exact description thereof.

This invention relates to corn husklng and cutting machines.

This invention is a division of my 00- pending application, Serial No.639,502, filed May 17, 1923, for corn huskers.

In machines of this general type in which husking rolls have beenprovided and adapted to receive the stalks and husks of the corn,difficulty has been experienced 1n securing the desired clean andshortcut for fine fodder, due to the wedging and clogging of thematerial between the cutter located below the rolls and the rollers, andalso due to wedging of the material between the cutters and the shearbar and associated parts.

A further defect in the machines as heretofore constructed, which hascaused considerable difficulty in their successful operation, has beendue to the fact that the stalks were frequently fed in such a manner asto be presented to the upwardly or rising knives of the cutter, thusburdening the cutter with the extra load of carrying the stalks over andforwardly against the shear bar. In other words, the cutter was requirednot only to sever the stalks and husks, but also to fold or crumple thestalks into a crowded position against the shear bar before such stalkscould be cut. The net result of these defects was an unusual amount ofpower required for the operation of a cutter, and a generallyineffective and inefficient cutting of the material to the extent ofrendering a clean short out impossible.

A further serious difficulty experienced with the machines, asheretofore constructed, was the relatively inaccessible mounting of thecutters, and considerable dismantling of other parts of the machine hadto be done before the cutter could be reached for adjustment or repair.

This invention is designed to overcome the above noted defects, andobjects of such invention are to provide a corn husking ma- 1924. SerialNo. 698,034.

chine in which all of the material is fed forwardly of a vertical planethrough the center line of the cutter, in which no material isfedrearwardly of the cutter, in which the cutter and the shear bar are l0-cated closely adjacent the rolls and beneath the upper ends thereof, inwhich there is no crumpling or throwing of the material upwardlyyandforwardly by thecutters, in which there is no wedging, in which thecutter executes a direct out upon the material independently of theshear bar .while such material is held by the rolls in addition to itscooperative cutting action with the shear bar, in which a clean cut,unobstructed and free, is secured by the machine, with a minimumexpenditure of power, in which the cutter head is so positioned as torender the knives and parts thereof readily accessible, and in which ashort clean cut is provided, whereby the desired fine fodder isobtained.

An embodiment of the invention is shown diagrammatically in theaccompanying drawing, in which The single figure is a vertical sectionalview through the upper end of the feed rolls showing the cutter andassociated parts in their relative position, the major portion of thestructural details of the huskin machine being omitted for the sake ofclearness. j I

The machine comprises a plurality of downwardly and forwardly slantinghusking rolls 1, which may conveniently be driven by means of bevelgears 2 carried at their upper end, and meshing with similar j bevelgears 3 mounted upon a transverse driving shaft 4. Adjacent the extremeupper end of the rolls a vertical plate 5 is provided and is equippedwith side flanges 6. A chute 7 cooperates with the plate 5 and formstherewith a feeding hopper 'located above and adjacent the upper ends ofthe husking roll.

Immediately below the upper ends of the husking rolls a rotary cutter 8is positioned. This cutter is provided with a plurality of knives 9detachably bolted thereto and having their rear ends seating againstprojection 10 integral with the main body of the cutter. The cutter isrigidly mounted upon a horizontal driving shaft 11 and it is to beparticularly noted that a vertical plane through the center line of thecutter passes 20 "which separate the corn from the .435 the axis of thecutterhoacu'the s" 3 rearvrardly of the feeding hopper so that allmaterial fed to the machine passes tor- Wardly of this vertical planethrough tne center line iofthe cutter, and thus no PT 5 terial is fed tothe rear portion or upwarc 1y traveling portion or" the cutter. A shearbar 12 is carried in a suitable bracing trans? member 13 and is mountedin front of the cutter, and in close proximityito the mives. A secondtransverse member fl is provided :-.:immediately adjacent andheneaththe'rolls wandis joined to the member 13 by means of a plate 15.This composite structure, theref "f016 Cconstitutes in ett'ect a shearbar and i 15; apron locatedzin:close'proxin'iity to "the upper endsotitherolls. I y

In the'operation not this inicliine the stalks of cor and. husks are'?the"feeding hopper to the hus inc; rolls 1, stalks and husksinthe'usual manner. The stalks and huslzsare passed directly between thefeed 'riolls and forwardly of thewertical plane- 5 it'hrough the centralline of the cutter. Thus J zzvlitwillrhe seen that the stalks fedthrough -.a :cleansharp cut, and wholly preventing I binding and Wedgmgot the stalks, as no extended length of stall: is allowed to gather.Futher, inasmuch as thou-pron 15, which guides the stalksto tne cutterliar *12,xis positioned snbstai ally radislly'to 1 at .thispointg'aswell as-througghout the entire cutting piath ot the .irnives willalso be *e 11-:sentediatapproximately right angles to the :cut.

-40 masMost obviously; a: minimum amount of cpoweri is required'for theoperation-ot 'this machine as all of the newer is used in the :cutting;action per se,' andis not Wasted in .needless Wedging-hinding or bendingof val dly under any unusual conditions, a iiklll fe-01"111Gll1l36f 16is secured'rearwardly of the vertical plane "through the center line. ofthe cutter. This inember or knife cooperates 'Wlth the lznives tl ot'thecutter .to-"sevcr any material that may inadvertently ed through beprojected upwardly'into this location,

with the usual practice in this field of Work,

and that the term cutting shall not. be given its strictestinterpretation asused in this specification, and in the claims. 7 i

It Will he'scen that a combined h'uslting I and cutting machine has seenprovided in Whrch .notniat'erial 1S fed rearwar'dly of the -cutter, 1nwhich the cutter executes a tree and unobstructed stroke upon thematerial,

' in which therezis no binding-tor Wedging'or crumpling :ot thematerial, in which aminimum amount cit/power 155 required, and in Whichthe cutter head and parts are readily accessible being positionedadjacent the rear' of the rolls.

Although "the invention has been described in considerable-detail, it isto be understood that theinvention may be variously-emhod1edand is,therefore, to he limited only as claimed.

' I claim: I I

1. A corn husking' and cutting: machine con'ign'ising plurality o :t'downwardly and forwardly slanting husking rolls, a rotary cutter lo'cated- :infmiedia-tely below I and closely adjacentthe upper ends of saidrolls, a

and an apron extending upwardly from said shear bar into proximity tosaid'rolls. 1 In a corn huslzing and cutting'i'nachine,

"the combination o1 apluralityct' down- Wardly "and forwardly slantinghushing rolls, a rotary cutter located immediately below and closelyadjacent the u'pper'ends oi the rolls, a shear har located in "front of631d cutter bar and-spaced lilODlStlldlOllS,

an apron ior guiding material tronrthe rolls to said shear bar and a"depend ng lnnt'e positioned at the'rear of sald cutter head topreventdischargooit uncut lnaterial from the cutter.
